Abstract:This research evaluated the properties of recycled asphalt binders from Wisconsin sources. Continuous grading
properties were measured for 18 recycled binder sources: 12 reclaimed asphalt pavement (RAP) sources and 6 recycled
asphalt shingle sources (RAS). The data were used to evaluate the binder replacement criteria contained in the 2011
Wisconsin Department of Transportation (WisDOT) Standard Specifications for Highway and Structure Construction using
a reliability analysis. This analysis considered the variability of both the design pavement temperature and the blended
binder in the mixture. Recommendations were made to improve the reliability of the low temperature grade of the binder in
the mixtures when recycled sources are used.
